EYELETING-MCHINE.

To all uf/Loin, z'tmay concern.' Be it known that I, PERLEY R. GLASS, a citizen of the United States, residing at Brookline, in the county of Norfolk and State of Massachusetts, have invented cer# tain Improvements in' Eyeletingi\/Iachines,A

of which thefollowing description, in con nection with theaccoinpanying draw-ings,

20 slets. vfrom the standpoint of the shoe inanufacinvention consists in a novel organization lisa specification, like vreference `characters on the drawingsindicating like parts in the several figures.

This invention relates to machines for :set-ting blind or invisible. eyelets in sheet material suchas theiippers of boots and shoes."

` In 'setting blind or invisible' eyelets by mechanism as heretofore .constructed difficulty 'has been encountered in securing consistently' the desired effect upon the eye- This has proved very objectionable turer because itlias necessitated the frequent removal and replacement of iinperfectly inserted eyelets, an operation which is perfor perforating the outer part of the quarter and clenching the barrel of an eyelet between the parts of the work. In the illustrated embodiment this organization coni prises a punching-tool having its punching end beveled or otherwise shaped to consti-V tute an upsetting surface. I have discovered that the end of' a punching tool which is tapered to forma cutting edge may-be utilized with good advantage foi` upsetting the end of an eyeflet barrel provided the eyelet is properly' guided into engagementv with such surface- Apuncliing tool of thilslcliaractor. lends itself with particular facility to lthe.requireinei'its vof the blind or invisible eyeleting,peraton'because the step of per@l v.

forating the outer portion of the quarter results in locating the upsetting surface at the proper point for clenching the barrel of 5a a n eyelet Yinserted through the lining portion. Another feature of theinvention consists in a support upon which -may oe placed a y shoe quarter comprising an outer and a lin- 60 ing portion in combination with a tubular punch movable to perforate the upper portion of the quarter while the latter is yieldingly backed up by the lining portion.r By carrying out the punching operation under G6 these conditions a hole is formed in the outer part of the' quarter having a cleanly cut- 'Iiiis is an important advantage incidenttotlie present invention and eliininates the ragged and niissliapen holes frequently' produced heretofore in blind or invisible eyelet work.

Another importait 'feature of the inventionconsists in means for forming a perforation in one portion of va shoe quarter in alinenient with a perforation previously formed in the other portion tliereof. Such 4means is believed to be broadly new as heretofore both'portions ofthe upper have been perforated in substantially a single operation. As herein shown, the desired result is effected by a male punching tool movable to enter the bore of Athe tubular punch and so to cut a. perforation in the lining portion by a punch and die action.

[Tho combina-tion of means for punching one portion 'of ashoe quarter at one time an'd'nieans for punching the other portion of the quarter at anothertiine is also believed to be novel. In this aspect of the inventionanother important feature consists in a tubular punching member and a solid punching nieniber one Aof which is constructed and arranged to perfoi'ate independently one. portion of a shoe yquarter and to perforate the other portion in cooperation with thc other punching member.

It is important to guide the barrelof the eyelet as it is inserted through the perforation in the lining portion and to direct it into engagement with the upsetting surface of the punch previously inserted through the louter portion. Any desired means may be employed for this function but as herein eis` shown, and in accordance with another feature of the invention, the male punching member serves this purpose.

l las it: forms the subject-matter of my c`olam pending application, Serial No 249,986, filed August 15, 1918.-

The features above' discussed and others incident to the inventionwill be best understood and appreciated from the following description of' a machine embodying the invention selected for purposes of illust 'ation and shown in the acconipanying drawing, in which,--

' Figure 1 is a view in perspective of the operating partsof an eyeleting machine in which the present invention is embodied;

Figs. 2, 3 and -l illustrate on a large scale the successive positions of the punching and setting tools in setting invisible eyelets;

Fig. 5 a view-1n perspective of the punching and setting-tools; I Fig (i is a view in perspective'of a portion of a shoe quarter havinginvisibleeyelets set therein. and

Fig. 7 is a view in perspective of an upsetting tool of modifiedl foi-ml The invention is herein illustrated as eml bodied in an eyeleting machine of the type disclosed inI Letters' Patent4 of the United States No. 1.228,768, granted June 5,1917, upon myprior application, although the invention is not. limited to that. machine or .to machines of any particular type. v f The machine frame 2 is suitably shaped to support the moving parts of the machine and provided with vertical guideways in which 'reciprocates the plunger G having adj'ustably mounted in its upper end the lower or eyelet carrying set 9. Secured to the plunger (i is a'split collar S having ears on 'its rear side through which extends a clampying bolt. This bolt is extended beyond the ears-of the split collar and forms the journal for a block 10.

. the feed frame is free to slide upon the rod Lev/asm guidewavs' for lthe plunger which Acarries at its lower end the'conibined punch and up` setting tool it). The plunger 3l is moved Vdownnrardly in the punching opera-tion. as

will be presently described7 and at the con-4 tool et() for feeding the work by slidingI the feeding fraaie transversely. To this end A the frame is provided with a rearwardly extending arm to which is pivotally secured a block S0.- 'The block 8() is received between the jaws of a forked arm 82 journaled upon a stationary vertical shaft 86 and connected to al sleeve 88 having an outwardly extending arm 90. The Vlatter is connected through a link 92 to any suitable formof spacing mechanism by which the desired feeding movement is imparted to thefe'ed fraaie and the tool 40.

A .cutting block 69 and a. work plate 7l are mounted upon the machine frame 2 and a presser foot .T2 is provided for holding the work in place between the feeding steps. A raceway l2() is also provided for supplying eyelets to the eyelet carrying set 9. The parts of the machinea above described, and those not herein shown, in structure and. operation correspond to the similar parts,of the eyeleting machine disclosed in my prior application above identified. Only suflicientparts of this machine have been illustrated to render clear the operation of the machine, the remainder having 'been omitted for the sake of clear-ness. e'

The punching and rupsetting tool 4'0 is provided with a threaded shank lllwliichis received within the lower end of the plunger Z'l-l. This tool is"'p'rimarily a tubular punch having its lower end i2 tapered to form a cutting edge and incidentally an upsetting surface as willpresently appear. .As shown in Figs. 2 to' the end 42 of the tool el() is beveled or tapered in a concave manner and above the tapered port-ion is a cylindrical portion 43. Above the portion 4 3 the tool is enlarged and provided with a .threaded port-ionll upon which is adjustably held a stop 45 which comprises a threaded nut.

The plunger 3l -and tool 40 are so constructed and arranged that when the plunger is depressed the cutting edge of the tool will be forced through the-outer portion 20 f of a shpeuquarter, or the upper layer of the work7 supported'upon the cutting 4block 69 as shown in F ig. 2 and will enter slightly the material of the layer 2l beneath. In order to render this operation more accurate the stop l5 is so adjusted upon the threaded portion l of the tooll() that the exposed length of the cylindrical portion 4&3 of the tool is substantially equal tothe thickness of the portion of the Work. It will thus be seen that`the lower layers :21.and 22 of the Work will constitute a yielding backing for the layer 20 Which is to be perforated by the tool 40. `As already pointed out the punching opera/tion under these circumstances produces a very cleanly punched hole in the upper portion 2() of the Work.

The eyelet carrying set 9 is shaped at its upper end to receive the flange-of the eyelet to be inserted and With an upwardly projecting punching member 11 of such diameter as to enter the bore of the tubular punchl ing tool 40. At its upper end the punching Y member. 11 is beveled aix-13 upon one side so that its punching action, m cooperation with the tubular punching member 4:0, Will be of ashearing punch and die nature. To insure more certainly the proper entering. of the punching member 1l inthe bore of the tubular punching member the opposite side of the upper end of the member 11 is slightly beveled'. rlhe punching member 11 occupies the position in the eyelet carrying` set 9 of l the usual center spindle and as such spindle it has the function lof taking an /eyelet from the racevvay and holding it in position during the upward movement `of the eyelet carrying set. In the present construction the punching member 1l also serves as a positive guide for directing the barrel of the eyelet throughthe lotv'er portion of the Work and into engagement With the upsetting sur- 'face upon theend 42 of the tubular punching tool. l

In operating the machmeherem illust-rated the shoe quarter is placed upon the Work plate `7l with the point at which the first eyelet is to be set above the cutting block 69`and in alinement with the tubular punching tool 40. The machine is then set in operation and the plunger 34 depressed carrying the tubular punching tool through the upper portion 20 ofthe quarter and embedding its end slightly in theunderneath vportion 2l ofthe quarter. 'Fig'. 2 of the drawing shows the punching tool in this position. The tool 40 is then moved trans, versely-toward the left feeding the entire quarter With it until it comes into a position in alinement with and above the eyelet carrying set 9. The plunger 6 is then elevated and an eyelet suppliedl to the punching member 11 during vthe upward movement thereof. The punching member 11 then en.-

-counters the undersidelof the lower portion 22 of the quarter and in. its upward moveout a hole in the previously. unperforated portions of the quarter. Fig. 3 illustrates the punching member llas partially enteredinto the bore of theftubular punch 40. As the upward movement of the eyelet carrying set 9 continues'the 'member l1 advancesu-p the bore ofthe tool 40 pushing the punchings ahead of it and at the same time gu1d .the tools reach their nal position, as shown in Fig. 4, the clenched end of the barrel is.

flattened down by the pressure'upon it of the material of the upper portion 20 reinforced by the lower face of the stop 45.

'The work herein illustrated comprisesa shoe quarter made up of an outer or leather portion 2O and a lining portion which in turn is made up lof a stitfening strip 21 of canvas `or similar material and a leather part :22. For convenience the invisible eyelet Will be described as being set in the lining vpart of the work` that is to say with its flange against one surface of the part'22 and its clenched end against the oppositely disposed surface of the stitfening strip Ql'but it will be apparent that if desired the eyelet may be set in one layer only of the wor t. This would be accomplished if the tubular punch 4:0 Wereadjusted to pass through the intermediate strip Q1 in its punching operation.

Fig. T illustrates a tubular punching tool having its cutting edge formed by a. convex instead of a concave bevel. A tool of this description has been found to operate advantageously upon certain classes of Work and may be substituted for the tool shown in FigsfQ to 5 Withoutl affecting the operation of the machine as above outlined.

ln the foregoing description the operation of setting an invisible eyelet has been described, such an eye-let being one set in the lining portion of a quarter beneath the hole-formed in the outer or leather portion'. The opeiatiorrofsetting a blind eyelet is similar in all respects except that the Work is presented' to the machine in an inverted position, .that is to say with the lining uppermost. -The eyelet then set will be 'disposed With its flange upon the outer surface of the shoe and its clenched end Within the lining portion so that only a holepfor the plzlissagefof the lacing appears within the s oe.
